System and method for controlling feathering mode of multi-rotor electric propeller in hybrid aircraft

The invention provides a system and method for controlling feathering mode of a multi-rotor electric propeller in a hybrid aircraft and belongs to the field of hybrid aircrafts. The system comprises a flight control system, two rotor arms, photoelectric sensors symmetrically mounted at two ends of the rotor arms, direct-current brushless motors, and a direct-current brushless electronic speed control; a rotor propeller is fixedly mounted above each direct-current brushless motor; the rotor propellers rotate with the direct-current brushless motors; the photoelectric sensors judge whether the rotor propellers are in feathering position or not according to whether light emitted is reflected or not, and output high and low level signals to the flight control system in order to perform detecting and logic computing, the flight control system outputs a corresponding control signal to the direct-current brushless electronic speed control, and the speed of the direct-current brushless motors is further controlled.
